Question

Find the critical value and rejection region for the type of chi-square test with sample size n and level of significance α $\alpha.$
 Right-tailed test, $\mathrm { n } = 20 , \alpha = 0.01$
A) $\chi ^ { 2 } 0 = 36.191 ; \chi ^ { 2 } > 36.191$
B) $\chi ^ { 2 } 0 = 27.204 ; \chi ^ { 2 } > 27.204$
C) $\chi ^ { 2 } 0 = 30.144 ; \chi ^ { 2 } > 30.144$
D) $\chi ^ { 2 } 0 = 32.852 ; \chi ^ { 2 } > 32.852$

Quizplus · Accepted Answer

The critical value for a chi-square test with $n-1 = 19$ degrees of freedom at $\alpha = 0.01$ significance level is approximately 36.191. The rejection region is $\chi^2 > 36.191$.
